Air-Spading: A Precision Root Diagnostic Tool
Air-spading removes soil using compressed air without cutting roots, exposing buried flares and girdling roots.
Scientific Notes:
Improves porosity and oxygen diffusion.
Helps identify pathogen-prone saturated zones.
Mimics natural soil loosening without mechanical injury.
Key Bullet Points:
Uses: Exposing root flare, correcting soil depth, diagnosing decay.
Benefits: Non-invasive, root-safe, improves soil structure.
Best Time: Growing season or mild weather windows.
5. Girdling Roots: How Roots Choke Their Own Tree
Roots that wrap around the trunk compress vascular tissues and disrupt nutrient flow.
Scientific Notes:
Phloem compression reduces carbohydrate transport.
Hormone flow (auxins) becomes restricted, altering growth.
Tree responds with asymmetrical canopy thinning.
Key Bullet Points:
Symptoms: Flattened trunk, no root flare, one-sided decline.
Risks: Trunk instability, early death.
Correction: Root pruning + air-spading; early detection is critical.
